Reckless fling? (11)
I believe the answer is:
precipitate
I believe this is a double definition.
'reckless' is the first definition.
(I've seen this before)
'fling?' is the second definition.
(thesaurus)
(Other definitions for precipitate that I've seen before include "Suddenly cause - condense and fall (as rain, sleet etc)" , "Pour" , "one making a deposit, perhaps" , "Headlong" , "rash" .)
